If the gender was passed as a "feature" in the machine learning model, then the company may have been biased. If not, then the majority of the women's CVs were inferior. This important information is not present in the article.
Why on earth would someone publish a paper like that? This is absolutely rubbish. A guy wanted to show the world how special he is because he writes Lisp, listens to jazz, and practices Aikido, and wrote a whole meaningless paper for that.
